我在安装PyGraphviz时遇到了麻烦。 我在Mac OS X中使用Anaconda。
错误消息表明某些原因，但我已经检查过它是安装在anaconda目录中的。
Sundongui-MacBook-Pro:site-packages sundong$ pwd
/Users/sundong/anaconda/lib/python2.7/site-packages
Sundongui-MacBook-Pro:site-packages sundong$ pip install graphviz --upgrade
Requirement already up-to-date: graphviz in /Users/sundong/anaconda/lib/python2.7/site-packages
根据错误消息，如何更改setup.py中的include_dirs和library_dirs变量？
以下是我遇到的错误消息
Sundongui-MacBook-Pro:anaconda sundong$ pip install pygraphviz

Your Graphviz installation could not be found.
1) You don't have Graphviz installed:
Install Graphviz (http://graphviz.org)
2) Your Graphviz package might incomplete.
Install the binary development subpackage (e.g. libgraphviz-dev or similar.)
3) You are using Windows
There are no PyGraphviz binary packages for Windows but you might be
able to build it from this source. See
http://networkx.lanl.gov/pygraphviz/reference/faq.html
If you think your installation is correct you will need to manually
change the include_dirs and library_dirs variables in setup.py to
point to the correct locations of your graphviz installation.
The current setting of library_dirs and include_dirs is:
library_dirs=None
include_dirs=None
error: Error locating graphviz.

假设您已经安装了 graphviz 软件：
如this blog post中所述，在尝试运行pip install pygraphviz
--install-option="--include-path=/usr/local/include/graphviz/" \
--install-option="--library-path=/usr/local/lib/graphviz"
所以最后的命令看起来像pip install pygraphviz --install-option="--include-path=/usr/local/include/graphviz/" --install-option="--library-path=/usr/local/lib/graphviz"。
这是明确指定的，其中存在python扩展使用的原始程序（graphviz）的库。不幸的是，这似乎没有得到自动识别。

尝试以下操作（确保安装并更新了anaconda-client）：
conda install --channel https://conda.anaconda.org/garylschultz pygraphviz
答案 2 :(得分：2)
Graphviz可以通过自制程序安装：brew install graphviz。
然后做：
cd /usr/local/Cellar/graphviz/VERSION/include/graphviz
mkdir graphviz
cp cgraph.h graphviz/
最后：
pip install graphviz
在Sierra和Woks上进行了测试。
答案 3 :(得分：0)
brew install graphviz
然后：
pip install --install-option="--include-path=/usr/local/include/" --install-option="--library-path=/usr/local/lib/" pygraphviz两个粗体路径都不应包含“ graphviz”。
